Photoshop: error code c0000005, program needs to close

when I try to start photoshop, the program starts to look for missing files and then shuts down with the message: error code c0000005, address 39e22109. I can not open the program as this happens each time i try to open Photoshop.

I have been using this version of photoshop without any problems for years. I have no idea what changed if anything.

However, the missing files message did come up a number of times before and then the program would boot up and continue. After several startups like that, the "missing files" error message would appear, the program searches for a while and then produces the error message " program needs to close" error code c0000005, address 39e22109. The program quits and when i try to restart the cycle repeats itself and then quits.

The only thing that I have done differently recently was that I have tried to use the "restore missing files" function, after which the problem seemed to appear.
